ASUS R-series APUs

22.05.2014

On May 20, AMD introduced the second generation of hybrid processors related to the R series. The processors are intended for embedded systems. Previously, these products were referred to under the code name Bald Eagle.

The purpose of the Bald Eagle platform is medical devices, gaming machines, information boards, industrial automation tools and other embedded systems that require high graphics performance.

The manufacturer positions the new products as designed for the middle and upper price segment. The new APUs support Windows, Linux OS and RTOS. The CPUs integrated in them on the AMD Steamroller microarchitecture operate at clock speeds of 2,2-3,6 GHz, and the GPU clock speeds on the AMD Graphics Core Next architecture lie in the range of 533-686 MHz.

Among the advantages of the new generation R hybrid processors, the manufacturer names the Heterogeneous System Architecture (HSA), which was first used in embedded processors. This architecture allows applications to distribute the workload between GPUs, CPUs, and dedicated accelerators in an optimal way, thereby achieving a significant increase in overall system performance. According to AMD, the new APUs outperform comparable Intel Core (Haswell) processors by up to 46% in compute performance and 44% in graphics performance.

The new processors are supported in the free open source software Sourcery CodeBench and Mentor Embedded Linux, as well as Mentor Embedded Linux Lite.

If we take into account the scope of new APUs, the guaranteed period of their availability at a commercial level is 10 years. The dual-channel memory controller built into the processor supports ECC memory (can run at DDR3-2133 speed), and the TDP value is configurable. All this gives system developers additional flexibility.

New APUs allow you to connect multiple monitors at the same time. With the addition of the AMD Embedded Radeon E8860 discrete GPU, up to nine displays can be connected while maintaining 4K resolution.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Olympus Tough TG-870 rugged camera 23.03.2016

The Japanese company Olympus has launched a new compact rugged camera series Tough - Olympus Tough TG-870 - with unique selfie capabilities in any conditions, even underwater.

The camera is protected in all respects: it can be immersed in water to a depth of 15 meters, thrown from a height of 2,1 meters, used at temperatures down to -10 ° C, the body also withstands a pressure of 100 kg and is dust resistant.

As for technical features, the Tough TG-870 has a wide-angle zoom lens with a focal length range of 21-105mm EGF, a 3-inch swivel display and a 16-megapixel back-illuminated CMOS sensor.

The unique 5-axis stabilization system allows you to take sharp pictures even in low light conditions that require slow shutter speeds. 13 artistic filters will help you to decorate your shots.

From the unusual - the camera is perfectly equipped for selfies. Firstly, the screen rotates 180°, which makes taking selfies especially easy. Secondly, the shutter button is duplicated on the front panel, which will allow you to hold the camera in the way that is convenient for you.

In addition to photos, the camera allows you to shoot video in Full-HD at 60 frames per second in progressive scan. By the way, due to the fact that its body is protected from water ingress, it will be possible to shoot amazing videos (and photos, however, too) from the underwater depths.
